With the arrival of summer in July, the heat scorches the earth, and there is no better time to cool off with watermelon and soft drinks in an air-conditioned room. However, when we are immersed in this comfort, the numbers on the electricity bill are often heart-wrenching.
Experts point out that when the outdoor temperature is as high as 30 °C or more, the larger the difference between the set temperature of the air conditioner and the ambient temperature, the air conditioner needs to run at high power for a long time to quickly reach the set temperature, which will naturally lead to an increase in power consumption. On the contrary, the smaller the difference between the set temperature and the ambient temperature, the lighter the operating burden of the air conditioner, so as to achieve the effect of energy saving. Therefore, from the point of view of power saving, it is more economical to choose 28°C as the set temperature than 26°C.
In fact, for every 1°C increase in the air conditioner, the electricity load can be reduced by 7% to 10%. This means that if we turn up the temperature of the air conditioner a little, we can significantly reduce our electricity bill. For example, if a 1.5 hp air conditioner is turned on for 8 hours a night and the temperature is set at 26°C, the monthly electricity bill is about 120 yuan, and when the temperature is set at 28°C, the monthly electricity bill is about 110 yuan, saving about 10 yuan. While this may seem like a small number, if you have multiple air conditioners running at the same time in your home, the savings on your electricity bill over the summer will be considerable.
In addition, we should also note that the comfortable temperature range of the human body indoors is between 25-28°C. During the day, due to the amount of activity, it may be more comfortable to set 26°C, but at night, when the body temperature drops periodically, it may be more appropriate to set 28°C and turn on sleep mode. This ensures a comfortable night's sleep and avoids catching a cold.

At the same time, we need to avoid going too far for low temperatures. Some people like to turn on the low-temperature air conditioner and cover it with a thick quilt, although it feels cool, but it is easy to cause air conditioning sickness for a long time, and will make the air conditioning compressor continue to work and shorten the service life. In order to be more energy-efficient and healthy, we can take some measures: such as setting the temperature to a high cooling state at the beginning of the machine to cool down quickly, and then turning it back to a lower temperature when the room is cool, using a fan to speed up the circulation of cold air in the room, and turning the air conditioner vent upwards to avoid discomfort caused by direct cold air.
In short, while enjoying the coolness brought by the air conditioner, we should also pay attention to energy conservation and health. By choosing the set temperature and taking some energy-saving measures, we can not only maintain a comfortable indoor environment, but also effectively reduce the cost of electricity.
